FIELD AND BACKGROUND OF THE INVENTION

The present invention, in some embodiments thereof, relates to cultured meat-containing hybrid food.

In recent years, attempts have been made to bring natural taste, odor, appearance and nutritional value of meat to the process of vegetarian food preparation, under the fields of food science, food technology and molecular gastronomy.

Cultured meat, also called synthetic meat, cell-cultured meat, clean meat, and in vitro meat, is meat grown in cell culture instead of inside animal, see Verbeke, Wim, Pierre Sans, and Ellen J. Van Loo. “Challenges and prospects for consumer acceptance of cultured meat.” Journal of Integrative Agriculture14.2 (2015): 285-294, which is incorporated herein as a reference. Several patent documents describe a variety of cultured meat consumable products and related method: US pat. app. Nos. 2005010965, 2006121006, and 2006029922 disclose process for production and cultured meat which comprises muscle cells that are grown ex vivo attached to either 2D or 3D support structure and further comprises other cells such as fat cells or cartilage cells, or both, that are grown ex vivo together with the muscle cells. The visual appearance (including color), smell, texture taste and price-per-product of the cultured meat published in the art is not yet satisfying, see Post, Mark J. “Cultured meat from stem cells: Challenges and prospects.” Meat Science 92.3 (2012): 297-301; Verbeke, Wim, et al. “Would you eat cultured meat?’: Consumers’ reactions and attitude formation in Belgium, Portugal and the United Kingdom.” Meat science 102 (2015): 49-58; and Forgacs, Gabor, Francoise Marga, and Karoly Robert Jakab. “Engineered comestible meat.” U.S. Pat. No. 8,703,216. 22 Apr. 2014, all incorporated herein as a reference.

It therefore remains a long felt and unmet need to provide a novel non-meat production method which is more cost-efficient than the current methods of production and non-meat products which are healthier having an improved meaty flavor and appearance.

Although methods and materials similar or equivalent to those described herein can be used in the practice or testing of embodiments of the invention, exemplary methods and/or materials are described below. In case of conflict, the patent specification, including definitions, will control.

DESCRIPTION OF SPECIFIC EMBODIMENTS OF THE INVENTION

The present invention, in some embodiments thereof, relates to cultured meat-containing hybrid food.

Before explaining at least one embodiment of the invention in detail, it is to be understood that the invention is not necessarily limited in its application to the details set forth in the following description or exemplified by the Examples. The invention is capable of other embodiments or of being practiced or carried out in various ways.

Whilst reducing the present invention to practice, the present inventors realized that enriching vegetarian foods with in vitro-cultured isolated animal cells that do not attempt to mimic a tissue structure can enhance organoleptic properties and nutritional properties of foods that are based essentially on plant-originated substances.

As used herein the term “organoleptic properties” refers to the aspects of food, that a consumer experiences via the senses—including taste, sight, smell or touch.

For example, adipocytes may be used to confer a non-meat food with a meaty taste and/or texture (e.g., beef or chicken) when cooked or grilled.

Cardiomyocytes may be used to confer a non-meat food with a texture of meat as well as taste (e.g., bitter/metal) of meat.

Erythrocytes may confer a non-meat food with a grilled meat (e.g., beef or chicken) taste as well as meaty color (e.g., beef).

Hepatocytes may confer a non-meat food with meaty color (e.g., beef) as well as enrich the taste of meat.

The term “meat” is meant to encompass any animal flash that is eaten as food (e.g., beef, pork, poultry, fish as well as additional examples which are provided hereinbelow).

In this case, the organoleptic property is that of meat. For instance, when referring to taste, an organoleptic property may be an umami taste.

As used herein “nutritional properties” refer to the composition of meat that is of valuable to the subject feeding on it.

For muscle tissue is very high in protein, containing all of the essential amino acids, and in most cases is a good source of zinc, vitamin B₁₂, selenium, phosphorus, niacin, vitamin B₆, choline, riboflavin and iron. Several forms of meat are also high in vitamin K. Muscle tissue is very low in carbohydrates and does not contain dietary fiber. Proteins, vitamins, and minerals are available from almost any source of meat and are generally consistent.

The fat content of meat can vary widely depending on the species and breed of animal, the way in which the animal was raised, including what it was fed, the anatomical part of the body, and the methods of butchering and cooking. Wild animals such as deer are typically leaner than farm animals, leading those concerned about fat content to choose game such as venison. The fatty deposits that exist with the muscle fibers in meats soften meat when it is cooked and improve the flavor through chemical changes initiated through heat that allow the protein and fat molecules to interact. The fat, when cooked with meat, also makes the meat seem juicier. However, the nutritional contribution of the fat is mainly calories as opposed to protein. As fat content rises, the meat’s contribution to nutrition declines. In addition, there is cholesterol associated with fat surrounding the meat. The cholesterol is a lipid associated with the kind of saturated fat found in meat.

Table A below compares the nutritional content of several types of meat (per 110 gr). While each kind of meat has about the same content of protein and carbohydrates, there is a very wide range of fat content.

TABLE A Source Calories Protein (gr) Carbs (gr) Fat (gr) Fish 110-140 20-25 0 1-5 Chicken breast 160 28 0 7 Lamb 250 30 0 14 Steak (beef top round) 210 36 0 7 Steak (beef T-bone) 450 25 0 35

Other major nutritional ingredients and their sources are provided hereinbelow:

Vitamin B12, which is mainly found in fish, meat, poultry and dairy products.

Vitamin D, which is found in oily fish, eggs and dairy.

Docosahexaenoic acid (DHA), which is an essential omega-3 fat found in fatty fish.

Heme-iron, which is predominantly found in meat, especially red meat.

Zinc, which is mainly found in animal protein sources, such as beef, pork and lamb.

Hence, the improvement/enhancement in nutritional property can be in any of protein, calories, fat, vitamins, minerals such as listed herein.

As used herein “enhancement”, “increase”, “augmentation” refers to an addition of at least 10 %, 15 %, 20 %, 25 %, 30 %, 35 %, 40 %, 45 %, 50 %, 55 %, 60 %, 65 %, 70 %, 75 %, 80 %, 85 %, 90 % 95 % 100 %, 200 %, 300 %, 400 %, 500 %, 600 %, 700 %, 800 %, 900 % or 1000 % (e.g., by weight or by score) of the organoleptic or nutritional property as compared to the same food without the cultured meat cells or in which a portion has been substituted with an equivalent amount of cultured meat cells (e.g., lipid portion, hydrolysate, synthetic additives etc.), as described below.

The terms ‘hybrid food’ and ‘products’ thereof refer hereinafter to a foodstuff or a portion of a foodstuff comprising at least one first non-meat significantly high portion and at least one second cultured meat low portion, combined (e.g., interconnected) with said at least one first non-meat portion.

According to a specific embodiment, the non-meat is a plant originated substance(s).

According to a specific embodiment, the non-meat is a non-plant originated substances (e.g., minerals, synthetic substance(s)).

According to a specific embodiment, the non-meat is selected from the group consisting of a plant originated substance(s) and non-plant-originated substance(s).

According to a specific embodiment, the foodstuff is a vegetarian foodstuff.

According to a specific embodiment, the foodstuff is a vegan foodstuff.

According to a specific embodiment, the foodstuff comprises a meat substitute or is generally consumed as a meat substitute (plant-based).

According to a specific embodiment, the animal cells are of a single cell type or single cell lineage.

As used herein “cell lineage” refers to any of endoderm, mesoderm and endoderm.

According to a specific embodiment, the animal cells are of no more than two cell types or two cell lineages.

According to a specific embodiment, the animal cells are of no more than three or four cell types.

According to a specific embodiment, the hybrid foodstuff is free of bodily fluids e.g., saliva, serum, plasma, mucus, urine, feces, tears, milk etc. As used herein “animal cells” refer to “non-human cells”.

The term ‘foodstuff’ refers hereinafter to any substance with food value; the term further refers to the raw material of food before, within the process and after processing, the food product or portions thereof (e.g., the coating of an edible item such as a schnitzel), by-product(s) and end-product (e.g., sausage, ground meat, schnitzel etc.) thereof. In the present invention, there are provided three families of foodstuffs: plant-originated foodstuffs and substances thereof, and cultured meat, cells and substances thereof, both are known in the art; and the novel hybrid foodstuff which comprises a majority (above 50 % w/w) of said plant-originated substances and a minority (below 50 % w/w) of cultured meat, cells and substances thereof interconnected with said plant-originated substances to form a unified foodstuff with an improved organoleptic and nutritional value.

According to an embodiment of the invention the hybrid foodstuff is an end article of manufacture (product) to be consumed by a human or non-human subject.

It will be appreciated that food refers to food or feed (animal feeding).

As used herein “cultured animal cells” refers to any non-human cell (e.g., mammals, avian, insect, fish) that is cultured in vitro but is not allowed to form a tissue in vitro.

The cells can be wild-type cells or genetically modified cells (e.g., transgenic, genome edited).

The term “cultured meat” is interchangeably used with “cultured animal cells”.

According to a specific embodiment, the cultured animal cells are terminally differentiated.

According to a specific embodiment, the cultured animal cells are partially differentiated (e.g., blood-derived mesenchymal precursor cells, neural progenitor cells, multipotent adult progenitor cells, mesodermal progenitor cells, spinal cord progenitor cells).

According to a specific embodiment, the cultured animal cells are stem cells (e.g., neural stem cells, multipotent stem cells from subventricular forebrain region, ependymal-derived neural stem cells, hematopoietic stem cells, liver-derived hematopoietic stem, marrow-derived stem cell, adipose-derived stem cells, islet- cells producing stem cells, pancreatic-derived pluripotent islet-producing stem cells, mesenchymal stem cells).

According to a specific embodiment, the cells are stem cells selected from the group consisting of mesenchymal stem cells and embryonic stem cells.

The phrase “embryonic stem cells” refers to embryonic cells which are capable of differentiating into cells of all three embryonic germ layers (i.e., endoderm, ectoderm and mesoderm), or remaining in an undifferentiated state. The phrase “embryonic stem cells” may comprise cells which are obtained from the embryonic tissue formed after gestation (e.g., blastocyst) before implantation of the embryo (i.e., a pre-implantation blastocyst), extended blastocyst cells (EBCs) which are obtained from a post-implantation/pre-gastrulation stage blastocyst (see WO2006/040763), embryonic germ (EG) cells which are obtained from the genital tissue of a fetus, and cells originating from an unfertilized ova which are stimulated by parthenogenesis (parthenotes).

Induced pluripotent stem cells (iPS; embryonic-like stem cells), are cells obtained by de-differentiation of adult somatic cells which are endowed with pluripotency (i.e., being capable of differentiating into the three embryonic germ cell layers, i.e., endoderm, ectoderm and mesoderm). According to some embodiments of the invention, such cells are obtained from a differentiated tissue (e.g., a somatic tissue such as skin) and undergo de-differentiation by genetic manipulation which re-program the cell to aquire embryonic stem cells characteristics.

The phrase “adult stem cells” (also called “tissue stem cells” or a stem cell from a somatic tissue) refers to any stem cell derived from a somatic tissue [of either a postnatal or prenatal animal (especially the human)]. The adult stem cell is generally thought to be a multipotent stem cell, capable of differentiation into multiple cell types. Adult stem cells can be derived from any adult, neonatal or fetal tissue such as adipose tissue, skin, kidney, liver, prostate, pancreas, intestine, bone marrow and placenta.

Hematopoietic stem cells, which may also referred to as adult tissue stem cells, include stem cells obtained from blood or bone marrow tissue of an individual at any age or from cord blood of a newborn individual.

Placental and cord blood stem cells may also be referred to as “young stem cells”.

Mesenchymal stem cells are multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells which give rise to marrow adipose tissue). The term encompasses multipotent cells derived from the marrow as well as other non-marrow tissues, such as placenta, umbilical cord blood, adipose tissue, adult muscle, corneal stroma or the dental pulp of deciduous baby teeth. The cells do not have the capacity to reconstitute an entire organ.

According to a specific embodiment, the cells are selected from the group consisting of erythrocytes, adipocytes, cardiomyocytes and hepatocytes.

According to a specific embodiment, the cells are erythrocytes.

According to a specific embodiment, the cells are adipocytes.

According to a specific embodiment, the cells are hepatocytes.

According to a specific embodiment, the cells are cardiomyocytes.

According to a specific embodiment, the cells are of domesticated animals, such as listed below (e.g., duck, chicken).

According to a specific embodiment, the cells are produced by in vitro expansion e.g., stem cell expansion.

According to a specific embodiment, the cells are produced by in vitro differentiation. Methods of cell differentiation are well known in the art.

Generally these methods are based on adherent cultures or suspension cultures, each of which is contemplated herein.

According to a specific embodiment, the cells are produced in a suspension culture.

In vitro meat can be produced by culturing the cells from farm animal species in large quantities starting from a relatively small number. Culturing satellite cells and even more so embryonic stem cells are typically for this purpose since these cells have an almost infinite self-renewal capacity. Recent reports have shown the establishment of stem-cell lines from domesticated ungulate animals e.g., non-human, rat, mouse (Challenges and prospects for the establishment of embryonic stem cell lines of domesticated ungulates. Anim Reprod Sci. 2007;98(1-2):147-168. doi: 10.1016/j.anireprosci.2006.10.009., which is hereby incorporated by reference). Bach et al. (Engineering of muscle tissue. Clin Plast Surg. 2003;30(4):589-599. doi: 10.1016/S0094-1298(03)00077-4.) suggested myosatellite cells as the preferred source of primary myoblasts because they recapitulate myogenesis more closely than immortal myogenic cell lines. Myosatellite cells have been isolated and characterized from the skeletal muscle tissue of cattle (Dodson et al. Optimization of bovine satellite cell derived myotube formation in vitro. Tissue Cell. 1987;19(2):159-166. doi: 10.1016/0040-8166(87)90001-2.), chicken (Yablonka-Reuveni et al. Dev Biol. 1987;119(1):252-259. doi: 10.1016/0012-1606(87)90226-0.), fish (Powell et al. Cultivation and differentiation of satellite cells from skeletal muscle of the rainbow trout Salmo gairdneri. J Exp Zool. 1989;250(3):333-338), lambs (Dodson et al. Isolation of satellite cells from ovine skeletal muscles. J Tissue Cult Methods. 1986;10(4):233-237. doi: 10.1007/BF01404483), pigs (Blanton Blanton et al. Isolation of two populations of myoblasts from porcine skeletal muscle. Muscle Nerve. 1999;22(1):43-50. doi: 10.1002/(SICI)1097-4598(199901)22:1, Wilschut et al. Isolation and characterization of porcine adult muscle-derived progenitor cells. J Cell Biochem. 2008;105(5):1228-1239.), and turkeys (McFarland et al. Proliferation of the turkey myogenic satellite cell in a serum-free medium. Comp Biochem Physiol. 1991;99(1-2):163-167. doi: 10.1016/0300-9629(91)90252-8). Porcine muscle progenitor cells have the potential for multilineage differentiation into adipogenic, osteogenic and chondrogenic lineages, which may play a role in the development of co-cultures (Wilschut et al. 2008, supra). Advanced technology in tissue engineering and cell biology offer some alternate cell options having practical applications and multilineage potential allowing for co-culture development with suitability for large-scale operations.

Alternatively, as mentioned, adult stem cells from farm animal species can be used. For instance, myosatellite cells are an adult stem-cell type with multilineage potential (Asakura et al. Differentiation. 2001;68(4-5):245-253. doi: 10.1046/j.1432-0436.2001.680412). These cells also have the capacity to differentiate into skeletal muscle cells. A rare population of multipotent cells found in adipose tissue known as adipose tissue-derived adult stem cells (ADSCs) is another relevant cell type for in vitro meat production (Gimble et al. Adipose-derived stem cells for regenerative medicine. Circ Res. 2007;100(9):1249-1260. doi: 10.1161/01.RES.0000265074.83288.09) which can be obtained from subcutaneous fat and subsequently transdifferentiated to myogenic, osteogenic, chondrogenic or adipogenic cell lineages (Kim et al. Muscle regeneration by adipose tissue-derived adult stem cells attached to injectable PLGA spheres. Biochem Biophys Res Commun. 2006;348(2):386-392. doi: 10.1016/j.bbrc.2006.07.063).

Matsumoto et al. (J Cell Physiol. 2007;215(1):210-222.) reported that mature adipocytes can be dedifferentiated in vitro into a multipotent preadipocyte cell line known as dedifferentiated fat (DFAT) cells, reversion of a terminally differentiated cell into a multipotent cell type. These DFAT cells are capable of being transdifferentiated into skeletal myocytes (Kazama et al. Mature adipocyte-derived dedifferentiated fat cells can transdifferentiate into skeletalmyocytes in vitro. Biochem Biophys Res Commun. 2008;377(3):780-785. doi: 10.1016/j.bbrc.2008.10.046) and are an attractive alternative to the use of stem cells.

For the sake of completeness some representative protocols for differentiation of specific cell types are provided herein.

Chicken Adipocytes Differentiation From ES Isolation and Cultivation of Chicken ES Cells

Isolation and cultivation of chicken ES cells can be carried out following previously described method (Wu et al., 2008 Wu XS, He XH, Dai MJ, Tian ZQ, Yang HY, Xu Q, Li BC (2008). Isolation and Cultivation of Chicken Embryonic Stem Cells and Production of Single-cell Clone. China Poult., 30: 30-34). In brief, blastoderm cells at stage X are collected by spoon method in tissue culture dishes and rinsed with Ca²⁺ and Mg²⁺ free PBS to remove the yolks and vitelline membrane. After washing with PBS, ES cells are transferred into fresh tissue culture dishes containing PBS plus 0.25 % trypsin and 0.04 % EDTA. Followed by digestion at 37 0° C. for 5 to 8 min, the dissociated cells are collected by centrifugation at 1000 r/min for 8 to 10 min and suspended, then about 3~5×10⁴ ES cells are maintained in a 5 % CO2 humidified atmosphere at 37 0° C. with DMEM and chicken embryonic fibroblast (CEF) cell monolayer. The medium is replaced daily with fresh medium. The cell colonies with undifferentiated morphology are rinsed three times with PBS and digested at 37 0° C. for 2 to 3 min with 0.25 % trypsin plus 0.04 % EDTA. The dissociated ES clusters are suspended with a pipette and subcultured in a 5 % CO2 humidified atmosphere at 37 0° C. with gelatin-coated flasks containing a feeder cell layer and DMEM medium. The medium is replaced daily with half fresh medium.

Induction of Chicken ES Cells Into Adipocytes

Chicken ES cells of the third passage are sub- cultured in DMEM medium with 10 % FBS for 48 h. The cells are induced firstly in an adipocyte induction medium with 10 % FBS, 5.5×10⁻⁵ mol/l β- ME(Sigma-Aldrich, Inc., St. Louis, MO, USA), 1×10-6 mol/L DEX (Maixin), 10 mg/ml Ins (Maixin), and 5×10-⁴ mol/l IBMX (Sigma) for 3 days and then in DMEM medium supplemented with 10 % FBS, 5.5×10⁻⁵ mol/L β-ME, 10 mg/ml Ins. After cultivation for an additional day, the medium is changed by induction solutions DMEM with GlutaMAX (Gibco, 31966-021) supplemented with 10 % of Hyclone FBS (Thermo, SH30070.03), 100× Non-Essential Amino Acid solution (Sigma, M7145), 100X Penicillin/Streptomycin (PAA, P11-010). Thereafter, the earlier step IS repeated three times. 21 days post-induction, the derived adipocytes are identified by oil red O staining as previously described (Yu F, Ge JH, Ni LG, He XH, Xu Q, Li BC (2008). In vitro Induction of Differentiation of Chicken Spermatogonial Stem Cells into Adipocytes. J. Agric. Biotechnol. 16: 450-455).

The basic medium is changed from DMEM to Iscove modified Dulbecco medium (IMDM; Gibco/BRL) 2 days prior to in vitro differentiation. Cells are grown without feeder cells. The medium is changed daily using mESC medium. The basic medium was is from DMEM to IMDM 2 days prior to in vitro differentiation.

Embryonic Body (EB) Formation

20 µL drops of the 1×10^(4c) cESC cells/mL suspension are placed onto the inner surface of 150 mm plate. They are incubated for 5 days and EBs are collected with 10 mL PBS into a 50 mL conical sterile tube. The EBs are allowed to sediment for 10-20 min at room temperature and PBS is removed. 0.05% trypsin is added to the cell culture and incubated for 2-7 min and Inactivated the trypsin by 2 mL differentiation medium. The EBs obtained from one plate are replated in 150 Place back in the incubator to 1-4 days.

Generation of ES Cell-Derived Erythroid Cultures (ES-EPs)

EB-derived cells at a concentration of 2×10⁶/mL are seeded into serum-free medium (StemPro34 plus nutrient supplement; Gibco/BRL) plus human recombinant erythropoietin (Epo; 2 U/mL; Erypo; Janssen-Cilag AG, Baar, Switzerland), murine recombinant Kit-ligand (KL or stem cell factor [SCF]; 100 ng/mL; R&D Systems, Minneapolis, MN), 10⁶ M dexamethasone (Sigma), and 40 ng/mL insulin-like growth factor 1 (IGF-1; Promega, Madison, WI). At day 1 and day 3 of cultivation, the suspension of cells is collected and replated into a new dish.

Cell density is maintained between 2 and 4×10⁶ cells/mL. ES-EPs are washed twice with PBS and cultivated at 2X10⁶ cells/mL in serum-free medium (StemPro34 plus nutrient supplement) supplemented with 10 U/mL Epo, insulin (10 ng/mL; Actrapid HM; Novo Nordisk), 3×10⁶ M of the glucocorticoid receptor antagonist ZK112.993,3 and one mg/mL iron-saturated human transferrin. ES-EPs derived from 6-day-old embryoid bodies are cultivated for 16 days under erythroid conditions, washed twice in PBS, and resuspended in IMDM.

An aspect of the invention also relates to a method of qualifying a hybrid foodstuff, the method comprising subjecting the hybrid foodstuff to at least one organoleptic test.

According to a specific embodiment, the hybrid foodstuff is any of the hybrid foodstuffs contemplated herein.

Methods of organoleptic assaying are well known in the art, some of which are described infra.

Organoleptic (sensory) evaluation is a common and very useful tool in quality assessment of processed food (e.g., meat) products, but to date not for hybrid foodstuffs. It makes use of the senses to evaluate the general acceptability and quality attributes of the products. The assays typically make use of dedicated panelists and/or artificial means.

All panelists must use proven and identical test methods in order to make their results comparable. Each panelist involved in such tests is given a scoresheet, where they mark their findings. Scoresheets of the team of panelists are evaluated and a test result for each individual product is produced based on multiple observations.

Common test methods used in sensory evaluation are:

1. Paired comparison test for simple difference where two coded samples are presented to the panelists for evaluation on simple difference (Table B).

2. Triangle test where three coded samples are presented at the same time, two are identical and the third is odd and the panelist is asked to identify the odd sample (Table C).

3. Hedonic scale rating test or acceptability test where samples are tested to determine their acceptability or preference (Table D).

TABLE B Score sheet for Paired-Comparison Test for Simple Difference Name: Product: Panelist No.: Date: Instructions: You are given a pair of coded samples, Indicate if there is a difference between them by placing an x mark under the appropriate column. Please write down any comments. SAMPLE PAIR CODE THERE IS A DIFFERENCE THERE IS NO DIFFERENCE Comments:

TABLE C Score sheet for Triangle Test Name: Product: Panelist No.: Date: Instructions: You are presented with three coded samples of ______. Two of these samples are identical while the third is odd or different. Smell and taste each sample. Indicate the code of the odd sample by placing an x mark across the code. Please write down any comments. SAMPLE CODE ODD SAMPLE Comments:

TABLE D Score sheet for hedonic-scale rating test Name: Product: Panelist No.: Date: Instructions: Taste the given samples, then place an x mark on the point in the scale which best describes your feeling. SCORE* SAMPLE CODE (9) Like extremely (8) Like very much (7) Like moderately (6) Like slightly (5) Neither like nor dislike (4) Dislike slightly (3) Dislike moderately (2) Dislike very much (1) Dislike extremely * Note: Numbers in parentheses are to be assigned during data analysis and are not to appear in the score sheet.

Tests for simple difference and the triangle test are very useful methods for quality control and product development. Newly formulated products can be evaluated by determining if a simple difference exists between the new products developed and the old ones. Similarly, the hedonic scale rating can be used for internal factory testing, and this method is also suitable for market research by determining the consumer’s acceptance or preference for certain products. Such a method i.e., the 9-PHS method is further described hereinbelow.

Instruments for Texture Measurement

Sensory testing (chewing) is normally sufficient to test tenderness/toughness or homogenous/fibrous structure of meat and meat products. If more objective results are desired, special instruments for texture measurement can be employed. Such a device typically measures the shear-force necessary to cut through meat/meat products. Comparative texture measurements are usually taken from same tissues or products which were submitted to different treatments such as ripening, cooking etc.

According to a specific embodiment, organoleptic assaying is effected by a combination of expert panel studies and by consumer difference and preference tests.

The expert panel studies may include two types of tests:

-   Difference testing - proving statistically the sensory benefits of     the hybrid foodstuff as compared to the corresponding product     without the cultured animal cells (substituted or not as defined); -   Quantitative Descriptive Analysis (QDA) - demonstrating how the the     hybrid foodstuff differs in specific sensory attributes from the     corresponding product without the cultured animal cells (substituted     or not as defined), with emphasis on the magnitude of meat related     texture and flavor characteristics.

Consumer studies will demonstrated how well the products are liked, which are preferred, and will quantify the effect of the SuperMeat on preferred sensory attributes.

Sensory Attributes

The list of relevant sensory attributes includes three main groups, adjusted individually per type of product, as follows:

Appearance: surface color, internal color, texture (coarsness, uniformity), overall rating with relevance to the type of product tested.

Texture: hardness/softness, juiciness/dryness, cohesiveness, chewiness, fatty/oily mouthfeel, overall rating.

Taste and flavor (possible list of positive and negative characteristics of aroma and taste): meaty, cooked chicken, roasted chicken, bouillon-like (brothy), greasy, burned, sweet, bitter, rancid, overall rating.

The detailed sensory list applies to the expert panel studies, mainly the QDA comparisons.

Selected and easily understood attributes in each sensory category (apperance, texture and taste) are used for the consumer acceptance and preference studies.

The Role of Cultured Heme-Poteins in Hybrid Foodstuffs

The two main heme proteins (HPs), hemoglobin and myoglobin, are important factors determining meat quality aspects such as color and hemorrhage, see Kranen, R. W., et al. “Hemoglobin and myoglobin content in muscles of broiler chickens.” Poultry science 78.3 (1999): 467-476; and see Boles, Jane Ann, and Ronald Pegg. “Meat color.” Montana State University and Saskatchewan Food Product Innovation, Program University of Saskatchewan (2010), which are both incorporated herein as a reference.

It is well in the scope of the invention where HPs are cultured in various methods, various sources, including, e.g., liver, bone marrow, mesenchymal cells or any other multipotent stromal cells that can differentiate into a variety of cell types, including osteoblasts (bone cells), chondrocytes (cartilage cells), myocytes (muscle cells) and adipocytes (fat cells); yet for convenient and in a non-limiting manner, one set of examples will be hereto disclosed.

Hepatocytes are enriched by those two main HPs and thus provide meat-like foods with improved organoleptic properties including meat-like color, texture, mouth feel, odor, flavor and appearance. Heme derived from the hepatocytes increasing bioavailability of the iron at about 24 % higher than that in food containing iron sulfate, see G. Gonzalez-Rosendo, et al., “Bioavailability of a heme-iron concentrate product added to chocolate biscuit filling in adolescent girls living in a rural area of Mexico,” Journal of Food Science, vol. 75, pp. H73-H78, 2010 which is incorporated herein as a reference.

In another embodiment of the present invention, six different novel hybrid foodstuffs are disclosed: (a) A chicken-flavored cultured-meat containing foodstuff, namely sausage-like hybrid food (I) and ground meat-like hybrid food (II), where the differentiated hepatocytes cells are cultivated to provide about 0.03% to about 0.07% HPs in the foodstuff; (a) A chicken-flavored cultured-meat containing foodstuff, where the differentiated hepatocytes cells are cultivated to provide about 0.1% to about 0.7% HPs; (b), A beef-flavored cultured-meat containing foodstuff, where the differentiated hepatocytes cells are cultivated to provide about 0.75 to about 2.5% HPs; (c) A chicken-flavored cultured-meat containing foodstuff, where the differentiated hepatocytes cells are cultivated to provide about 0.1% to about 0.3% oxymyoglobin; (d) A chicken-flavored cultured-meat containing foodstuff, where the differentiated hepatocytes cells are cultivated to provide about 0.1% to about 0.3% myoglobin; (e) A chicken-flavored cultured-meat containing foodstuff, where the differentiated hepatocytes cells are cultivated to provide about 0.1% to about 0.3% metmyoglobin; and (f) a combination (2.5% in total) of the same.

As mentioned, cultured cells can be used in their native form in the hybrid foodstuff or treated or genetically engineered to enrich a certain trait/phenotype e.g., level of expression of HPs.

Methods of genetically modifying cells are well known in the art.

Table 3 below describes potential results for assessment of sausage-like hybrid food (I) and ground meat-like hybrid food (II) cultured meet-containing hybrid foods as can be measured by 9-point hedonic scale (9-PHS).

The assay can be executed on individuals of the following characterization N= 25, age 30-65 yrs, about 50% male,

Table 3 above hence demonstrates the potential of in vitro produced HPs in cultured meat containing hybrid food and the synergic role of mixtures thereof in some of the foods, where improving food organoleptic features is to be shown.

The hybrid food is characterized by relatively high nutritional value. It provides with useful in administrating an effective dose of nutritional supplement, vitamins, minerals and proteins, e.g., those which inter alia selected from the group consisting of vitamins E, thiamine (B-1), riboflavin (B-2), niacin (B-3), pantothenic acid (B-5), B-6, biotin (B-7), folic Acid B-9, B-12, A, C, D, K, magnesium, iron, zinc, omega-3 fatty acids, creatine, carnosine and mixtures of the same.

The hybrid cultured meat and products thereof are enriched to some degree, when required, with additives to protect or modify its flavor or color, to improve its tenderness, juiciness or cohesiveness, or to aid with its preservation. Cultured meat additives hence potentially include, inter alia, salt and other means to impart flavor and inhibits microbial growth, extends the product’s shelf life and helps emulsifying finely processed products, such as sausages. Nitrite is utilizable in curing meat to stabilize the meat’s color and flavor, and inhibits the growth of spore-forming microorganisms such as C. botulinum. Phosphates used in meat processing are normally alkaline polyphosphates such as sodium tripolyphosphate. Erythorbate or its equivalent ascorbic acid (vitamin C) is utilizable to stabilize the color of cured meat. Sweeteners such as sugar or corn syrup impart a sweet flavor, bind water and assist surface browning during cooking in the Maillard reaction. Seasonings impart or modify flavor. They include spices or oleoresins extracted from them, herbs, vegetables and essential oils. Flavorings such as monosodium glutamate impart or strengthen a particular flavor. Tenderizers break down collagens to make the meat more palatable for consumption. They include proteolytic enzymes, acids, salt and phosphate. Dedicated antimicrobials include lactic, citric and acetic acid, sodium diacetate, acidified sodium chloride or calcium sulfate, cetylpyridinium chloride, activated lactoferrin, sodium or potassium lactate, or bacteriocins such as nisin. Antioxidants include a wide range of chemicals that limit lipid oxidation, which creates an undesirable “off flavor”, in precooked meat products. Acidifiers, most often lactic or citric acid, can impart a tangy or tart flavor note, extend shelf-life, tenderize fresh meat or help with protein denaturation and moisture release in dried meat. They substitute for the process of natural fermentation that acidifies some meat products such as hard salami or prosciutto.

It is thus within the scope of the invention wherein the hybrid food additionally comprising Acidity regulators, Acidity regulators, Anticaking agents, Anticaking agents, Antifoaming agents, Antifoaming agents, natural and other Antioxidants, Bulking agents, Food coloring agents, color retention agents, Emulsifiers, Flavors, Flavor enhancers, Flour treatment agents, Glazing agents, Humectants, Tracer gas, Preservatives, Probiotic microorganisms, Stabilizers, Sweeteners, Thickeners and any mixtures thereof.

Meat-Flavored Hybrid Foodstuff Free of Harmful Substances at Harmful Quantities

Meat is generally regarded by nutritionists as a healthy component of a well-balanced diet if eaten in moderation, although it’s clearly not essential, as vegetarians have proven for eons; see Johnathon Andrew “Benefits & Disadvantages of a Meat Diet” in the currently available link //livehealthy(dot)chron(dot)com/benefits-disadvantages-meat-diet-1908(dot)html(dot). Meat is an excellent source of protein and contains many of the vitamins and minerals that people need. On the other hand, meat is relatively high in fat and cholesterol, which are linked to increased risk of cardiovascular disease.

Meat Diet: Meat is typically defined as the flesh, muscle tissue and organs from animals, particularly mammals such as cows, pigs and lamb. Birds such as chickens and turkeys are often classified generically as meat, but sometimes differentiated as poultry. Fish has its own category and is not usually referred to as meat. According to the Harvard School of Public Health, meats should be placed at the very top of any food pyramid, which signifies they should be eaten sparingly and in small portions. In comparison, poultry and fish are usually placed further down on food pyramids, reflecting higher consumption recommendations and greater health value.

Main Benefits: Meat is an excellent source of protein in terms of both quantity and quality. For example, a typical 3-ounce portion of meat contains about 21 grams of protein, which is almost half the recommended dietary allowance for women each day. Meat is also a complete protein source because it contains all the essential amino acids your body cannot make. Amino acids are important building blocks for most tissues, such as muscle and skin, as well as enzymes. Meat is also a very good source of certain vitamins and minerals, especially most B vitamins, iron, zinc and phosphorus. Additionally, the density and caloric value of meat usually satisfies hunger better compared to equivalent amounts of vegetable foods.

Main Disadvantages: The main disadvantages of eating meat are pertaining with ethical considerations, including moral (e.g., killing animals), cultural and religious (Kosher and Halal issues, for example) highly important issues. Other disadvantages are related to the fat, cholesterol and sodium content. People need some dietary fat and cholesterol on a regular basis for energy and to make cellular membranes and certain hormones. However, meat is relatively high in saturated fat and cholesterol, which increase the risk of cardiovascular diseases such as heart attack and atherosclerosis. Sodium is also a serious concern because too much leads to high blood pressure and increased risk of stroke and heart failure. On average, processed meat contains approximately 310 milligrams of sodium per ounce, whereas unprocessed meat has about 77 milligrams. Younger adults should aim for less than 2,300 milligrams of sodium daily, whereas elderly adults and those with risk factors for hypertension should consume less than 1,500 milligrams per day.

Modest to aggressive changes in diet can improve health and reduce annual national medical expenditures by $60 billion to $120 billion, see Doll, Timothy M., et al. “Potential health benefits and medical cost savings from calorie, sodium, and saturated fat reductions in the American diet.” American Journal of Health Promotion 23.6 (2009): 412-422 and to Karppanen, Heikki, and Eero Mervaala. “Sodium intake and hypertension.” Progress in cardiovascular diseases 49.2 (2006): 59-75 both are incorporated herein as a reference. They have estimate that permanent 100-kcal reductions in daily intake would eliminate approximately 71.2 million cases of overweight/obesity and save $58 billion annually. Long-term sodium intake reductions of 400 mg/d in those with uncontrolled hypertension would eliminate about 1.5 million cases, saving $2.3 billion annually. Decreasing 5 g/d of saturated fat intake in those with elevated cholesterol would eliminate 3.9 million cases, saving $2.0 billion annually. Likewise, according to Kalmijn, Sandra, et al. “Dietary fat intake and the risk of incident dementia in the Rotterdam Study.” Annals of neurology 42.5 (1997): 776-782 which is incorporated herein as a reference, high intakes of the following nutrients were associated with an increased risk of dementia: total fat (RR = 2.4% intake as percentage of total energy intake), saturated fat (RR = 1.9%) and cholesterol (RR = 1.7%).

Hybrid foods of the present invention comprises significantly less quantities of harmful substances, such as cholesterol, fat and saturated fat, as shown in Table 4 below.

Hence, the present invention discloses a beef-flavored hybrid foodstuff free of harmful substances at harmful quantities; wherein said harmful substances including cholesterol, total fat and saturated fat; wherein harmful quantities are <60 mg, <8 gr and <3.5 gr per 100 gr, respectfully; and wherein said beef-flavored hybrid foodstuff comprises from about 82% to about 99% (w/w) plant-originated substances and additives thereof and about 1% to about 18% (w/w) cultured meat.

The present invention also discloses a pork-flavored hybrid foodstuff free of harmful substances at harmful quantities; wherein said harmful substances including cholesterol, total fat and saturated fat; wherein harmful quantities are <60 mg, <5 gr and <1 gr per 100 gr, respectfully; and wherein said pork-flavored hybrid foodstuff comprises from about 82% to about 99% (w/w) plant-originated substances and additives thereof and about 1% to about 18% (w/w) cultured meat.
